        DTE ENERGY/MCN ENERGY TO RECEIVE FTC CLEARANCE FOR PENDING MERGER

         DETROIT - DTE Energy (NYSE: DTE) and MCN Energy Group (NYSE: MCN) have
been informed that the Federal Trade Commission (FTC) will announce shortly
clearance for their proposed merger announced in October 1999. The action, which
is available for public comment for a 30-day period, provides FTC authorization
for the companies to close their transaction and places the companies yet
another step closer to completing their merger and creating a new combined
energy company under the DTE Energy name.

         The proposed merger still awaits Securities and Exchange Commission
(SEC) approval and approval by MCN shareholders of the recently amended merger
agreement. The special meeting of MCN shareholders is expected to take place in
the second quarter.

         "While this transaction has taken longer than originally anticipated,
this FTC action is a major step forward in this process and toward creating one
of the region's premiere energy companies," said Anthony F. Earley Jr., DTE
Energy chairman and chief executive officer. "We have spent more than a year
developing and reviewing the synergies and processes that will establish this
new entity as a solid player in the increasingly competitive energy market."

         The FTC staff had initially raised concerns regarding possible
competition between Michigan Consolidated Gas Company (MichCon), MCN's natural
gas utility, and DTE Energy's Detroit Edison electric utility for a narrow class
of electric displacement applications in their overlapping retail distribution
area. The companies have entered into a consent decree with the FTC, under which
MichCon will transfer a property interest in its pipeline capacity to a unit of
Exelon Corp. (NYSE:EXC) under a previously announced contract. The contract,
which allows Exelon to utilize natural gas transportation capacity on MichCon's
system within the relevant distribution area, remains subject to consummation of
the merger.

         "The FTC's action comes as welcome recognition of the efforts of the
team of employees who worked so diligently to craft a first-of-its-kind solution
to the FTC's concerns," said Alfred R. Glancy III, chairman and chief executive
officer, MCN Energy Group. "For those who might believe otherwise, however, the
FTC clearance was fully expected and did not factor into our decision to
renegotiate the terms of our merger agreement. Uncertainty over the length of
the Securities and Exchange Commission's review under the Public Utility Holding
Company Act was the key factor in our board's decision to renegotiate."

         With receipt of the FTC clearance, the companies now are in a position
to step up integration efforts and take actions to realize merger synergies as
soon as possible. While both companies hesitate to speculate on the timetable
related to the remaining approval process, they have indicated that they would
hope the merger could be completed this summer.

         "We are confident that the strategic benefits encompassed by the merger
and the increased value afforded both companies' shareholders are now well
within reach," said Earley.
